Product DescriptionProduct DescriptionProduct Description of FTB Fluidized Bed CoolerThe FTB Fluidized Bed Cooler is a high-efficiency, energy-saving, and eco-friendly sand cooling system based on the fluidization principle, specifically designed for rapid cooling of hot resin sand, reclaimed sand, or coated sand in foundries. Clean cold air passes upward through a perforated plate, suspending sand particles in a "boiling" state within the bed, enabling full, uniform, and efficient heat exchange between sand and air. It rapidly cools sand from 100–120°C down to ≤45°C, meeting process requirements for subsequent mixing, molding, or storage.The fully enclosed design combined with a pulse cartridge dust collector prevents dust leakage during cooling—ensuring compliance with national emission standards (≤5 mg/m3). The cooled sand exhibits stable temperature, uniform moisture, and excellent flowability, significantly improving mixing quality and molding efficiency. It is a core cooling component in the sand handling system of modern green foundries.Working PrincipleFeeding Stage Hot sand enters the fluidized bed via feed chute or pneumatic conveying, with sand layer thickness controlled by an automatic adjustable weir to ensure uniform distribution.Fluidized Cooling StageHigh-pressure cold air, driven by a centrifugal fan + air filter, enters the plenum chamber and passes through a perforated distributor plate (or ceramic plate), suspending sand particles in a fluidized "boiling" state. Full contact between sand and air enables efficient heat transfer, with heat carried away by the air.Discharge & Dust Removal Stage Cooled sand continuously discharges via overflow weir or adjustable gate to downstream conveyors or silos. Dust-laden exhaust gas is purified through an upper dust chamber + cartridge filter before emission, with dust recovery >99.5%.Intelligent Air & Temperature Control Equipped with temperature sensors (inlet/outlet) + differential pressure sensors + VFD-controlled fan, enabling automatic airflow adjustment for stable, controllable sand temperature and energy efficiency.Key FeaturesHigh Cooling Efficiency, Rapid Temperature DropCooling capacity: 2–30 t/h; cooling time: 2–5 minutes; temperature drop: 60–80°C—significantly improving production rhythm.Uniform Cooling, Stable Sand QualityFluidization ensures every sand grain contacts cold air—no "hot/cold pockets"; post-cooling temperature variation ≤±2°C, minimal moisture loss, excellent flowability.Fully Enclosed, Dust-Free & Eco-FriendlyEnclosed design + high-efficiency cartridge filter; dust emission ≤5 mg/m3, noise ≤80 dB(A)—compliant with GB 16297, GB 12348.Energy-Saving, Low Operating CostVFD fan + optional heat recovery system saves 30–50% energy compared to rotary drum coolers—adjustable airflow prevents waste.Wear-Resistant, Easy MaintenanceDistributor plate, liners, and discharge areas use ceramic, polyurethane, or NM400 alloy steel; modular design allows easy inspection and long service life.Intelligent Control, Remote MonitoringOptional PLC + HMI touchscreen + remote monitoring for automatic control of temperature, airflow, alarms, and data logging—supports MES integration.Main Technical SpecificationsParameterSpecificationModel SeriesFTB-1000 / FTB-1500 / FTB-2000 / FTB-3000CapacityDepending on sand temp & ΔTInlet Sand Temp80 – 120°COutlet Sand TempAdjustableCooling MediumClean ambient or chilled airFan PowerVFD-controlledTotal Power8 – 80 kWWeight3–25 tonsDimensionsCustomized by modelDistributor MaterialPerforated steel/ceramic/SS meshControl SystemManual / Auto / PLC+HMI / RemoteProtection RatingIP54/IP65 for control panelTypical ApplicationsSand temperature regulation before resin sand mixersRapid cooling of hot reclaimed sand after reclamationCooling and screening of coated sand (shell sand) in production linesIntegrated with central sand supply and automated molding lines for precise temperature controlCooling and drying of powders in chemical, food, and pharmaceutical industriesCompany ProfileQingdao Dingli Machinery Co., Ltd.Qingdao Dingli Machinery Co., Ltd. is a company specializing in the production of casting machinery equipment.
